Thanks for the quick response! I have had one on my shopping list for a longtime and I have been looking for an excuse to buy one. In this case, I am building about 16 drawer boxes out of 12mm baltic birch and was looking to drive brads at the joints (with glue and dominos). I also figured it would come in handy with other tasks, including trim work, cabinets, etc. It appears that the big box stores have a bunch of combo deals going on for Xmas, but I am getting lost in the online reviews. For example, Metabo vs. Bostitch; quality of Senco has declined; pancake compressors are too loud, etc. Also not sure, in teh long run, if combo deal is better than buying separately...you can pick and choose what is best. I get the whole 23G pin nailer craze, but I figured the 18G is more versatile and I can always grab one later when I may need it for a new project. However, another consideration is that I am just a hobbiest (also quickly realizing its a very expensive hobby) and don't want to spend more than $250.
BTW - I just bought the 'GRS-16PE' and absolutely love it! I wish I bought one when I bought my TS55.
