I dont think you state the exact model of the Rigid, that makes a difference in whether fixing it is worth it.
For a 1000.00 there are several saws that are very nice! For the money and a 1000.00 no question I would get one of the Grizzly saws that have fantastic reviews or the Craftsman. Finding the right model from them is important.
My wife purchased me a Craftsman hybrid for Christmas years back and even dragged it in the shop herself so it really is hard for me to think of replacing it. It has been a fantastic saw, made in China I don't care, this thing is perfect. When they are on sale you can get them for a steal of 799.00. I put the WWII thin kerf blade on it, a link belt, a large Incra fence and a 10 foot wide table with built in router tops on each side. I have never stalled the motor ripping 2" thick Cumaru, Ipe and other exotic hardwoods and after 6 years there is still not one thing wrong with it. It passes the balance a penny trick on edge easily too. The dust collection is average, not spectacular.
Some people claim it needs more power, one guy said it has trouble cutting 3/4" Oak, obviously he does not know what the heck he is doing and the saw is out of alignment or he is using the stock blade, etc, etc. IMHO for a hybrid you MUST use thin kerf bade if you want to cut thick hardwoods, if you want the thick blade go 3 hp. Yeah, compared to a 3hp it is underpowered, but the kickback is not where near as severe as the larger saws either. It also comes with the Biesmeyer fence stock, which is sweet. The miter gauge is a throw in and not the best, but not even close to the worst at all. I use an Incra 5000 or a custom set up I made. Nice thing about this hybrid is that it is cabinet mounted for easy to get perfect alignment, some of the hybrids are not, watch out for that. The wood table is crap toss it out. I replaced mine with a cast iron extension with the router mount. I am not sure what they give with the granite version as a side ext table. The out feed table is crap too, I never attached it, but it seems to work for some.
The saw has an option of the granite top now as well and there are 2 model numbers, one model is better than the other, I will track that down.

These are not Festool quality or Powermatic 66 or Saw Stop type saws. But for a 1000.00 and for me personally any of them are well worth it.
