I was in PRECISELY your situation in 2000 and have felt your pain. I read a 1-year taught masters degree in Comp Sci and haven't looked back. I paid back the costs of the degree within 3(ish) years, including the year of "lost" salary where I wasn't paid for study. This included a 2-year stint where I was underpaid compared to the average junior developer, and this was immediately post the 911-attack where the job market in the UK wasn't exactly fantastic. If possible I'd go for a pure Comp Sci degree, the web ones

As ever, there are a few caveats :

• Make sure your finances can withstand the costs & time taken out to study
• Don't believe the average graduate wages claimed for a new developer by your university. There are a few graduates who get taken up by the large consultancies who get paid a whack-load of dosh, this skews the average upwards. If you get a well paid job, you're in clover.
• You'll still have to deal with lusers, and they don't get any cleverer when you're trying to get specifications (or common sense or abstract thought) out of them
• You should be learning new technologies at home anyway...
