Harmon,
Bubba is correct: the router is indeed a DeWalt 2 1/4 HP plunge router, I think 621 is the model number. I love it. If I were in the market now, I'd also look at the new P-K 2 1/4 HP models (890?), which are just coming out to very good preliminary reviews.
I'm not sure whether the "attachment" you're referring to is the base or the router bit. If the base, it's a Jasper Jig base, which I keep attached more or less all the time because I like the extra stability and visibility it provides. If you're referring to the bit, I use a Whiteside 3-flute flush trim bit from
http://www.routerbits.com -- pricy but superb. I don't fool around with router bits -- they're spinning at 20,000 RPM!
The clamps are Jorgensen Cabinet Masters -- ridiculously expensive but an utter joy to use. For Christmas and birthdays, I tell everyone I know who's going to be getting me a present to get me one, and I've amassed about a dozen.
I stole the iron from my mother-in-law. I think it's a GE she bought at Walmart . . . .
Happy listening!
