Update - swung by Woodcraft yesterday. The Festool guy essentially acted like I was full of crap when I said ETS EC 125 with an additional 6" pad. Usually the Woodcraft guys are fairly knowledgeable, but this and a few other things he said made me question if I speaking to a salesman and not a woodworker. I ended up getting the ETS EC 150/5, not because of anything he said. I've got more than one router just because I don't fancy removing the one on my router table to use by hand. I'll get some box store item to use up the paper. It's good paper and that makes a big difference. Festool guy also tried to sell me the CT 15 (it's so tiny!), but I'll be going with the Hercules dust extractor. The hose does fit, if it annoys me I'll upgrade to the Festool hose. Sadly they didn't have the EC 150 in stock so I have to wait 2 weeks for my sander to arrive.
@luvmytoolz @Cheese I've got a mixture of Cubitron and Duragold. The Duragold is in a variety of grits, but mostly in the upper end automotive 1000s and no hole stick on paper for the blocks. The Cubitron is not the extract paper, it's got a weird water sprinkler pattern. tiny holes. I swear I'll use it up, hahaha! I haven't bought 6" any paper yet for the EC 150. Is there any Mirka or 3M paper you'd recommend? 3M seems fairly straightforward (and I'm already in love with it). Mirka has so many options named after locations in fantasy novels, I have no idea what the names mean.
The only issue with the ETS EC 125 is that it only comes in 3mm orbit (I REALLY wish it came in 5), so going with the ETS EC 150/5 was really the best route.
While I understand the reasons to go with the Hercules, there's a couple reasons to reconsider. The Hercules came out the weekend that I was going to buy my CT MIDI I (the glorified CT 15), so I was incredibly tempted to save some cash and get the Hercules (especially then because it was $249). But I had already been planning to get the MIDI and decided to stick with it. I have not regretted that decision.
The Hercules offers a lot of important features: onboard tool power, auto tool on, timed shutoff, variable suction, and HEPA filtration being some of the most important. It also is basically a shop vac with shop vac level suction power - this is a plus as far as shop vac-ing around your shop and when connecting to tools that need alot of suction, like a table saw, but may be too brute a force for sanding when you want to lower the suction to the lowest levels. The 6.5hp motor also draws more power - which means that the onboard power supply is more limited (the motor takes up 11.5 amps leaving 3.5 amps for the tool). Depending on what you want to connect, this could limit your options.
For example, I was finishing up a bandsaw restoration today and the MIDI was next to me, so rather than get up and plug the bandsaw into an outlet, I just plugged it into the MIDI and turned it on. Since I'm using the onboard power, the vac starts up along with the 7.8ampl 1/2hp bandsaw motor with no issues. I don't think the Hercules can do that.
I do like the 12ga capacity vs the 4ga of the CT15 but it also makes it larger and more unwieldy to maneuver and park around the shop, and I've found the stackability of the hose garage to stack systainers, TopRock and a CT-VA-20 to be very useful. Then there's the bluetooth - I thought it would be dumb when my guy at Woodcraft was trying to convince me on the wisdom of the MIDI over the 15, but now shoplife would be joyless without it. Then there's the D27 hose. Aside from the woven exterior and antistatic, the Festool connector just makes it easy. When I started with Festool, my friend had the ETS EC 150/5 and we connected it to a Ridgid shop vac and that 2.5" hose with adapter kept popping off - infuriating. So much better when everything works without fuss. You can get the 5m D27 hose for $189 which puts you right around $550 with the Hercules. For that kind of money, you can easily have the CT15 or CT25, and then for about $130 more you'd have the CT MIDI I.
Just some thoughts to consider from someone who almost bought the Hercules over the MIDI.
