The 10 board minimum doesnt really apply with some places like BatchPCB.com, if youre willing to wait. Theres a 10$ minimum and $2.50 per sq in so for small simple boards its not that bad to pay something like $15 to avoid the hassle of wiring perf boards. I cant tell you how much I despise wiring perf boards or hand-etching my own pcbs! Yeah itll take a week to get through the learning curve of Eagle but once you know it, its like riding a bicycle. So I guess I would suggest if this is a one off thing that just needs to be done quickly, it's not too bad to wire up a single perf board. But if this is something you might be doing again in the future and you have the time, I would suggest looking into making your own pcbs.
