I don't have a suggestion for single-sided boards BUT I've got to ask
why you would think AP Circuits was still the best option for online
PCBs? For example, SFCircuits.com has similar prices but includes
silkscreen and soldermask. There are many others which do the same. If
you look for specials which they run sometimes, you can get full
double-sided PCBs (soldermask, silkscreen ,etc.) for a fair amount
less than AP Circuits.
