Seawin22, I don't know where you live, but I got a TW certificate from Middlesex Community College in Bedford, MA, in 1999. It's an excellent, very highly-rated program. I landed a job at (then) Compaq right away, stayed there for 5 years (through the HP merger/acquisition), moved on to a couple of contracting gigs, then another full-time, direct position at my current company. It has served me extremely well. Absolutely the best career move I ever made.
