Ausburger eBay I love tayda and their cheap Vero but this seller has thick 1.6mm fr4 white Vero that's tinned and it looks and feels quality. They also have cheap bigger sheets. I'm weird about stripboard but I like this guys. I just ordered 20 sheets of the fr4 kind and it was in my mail box within 10 days. Now be aware its a bit expensive if you buy one or two but message and they'll adjust price if you buy a lot. Also It might be vastly cheaper for the euro guys to get real Vero.
MKlec We can't forget these guys. The main page is tied in with them thru kits. I love these guys and its crazy fast because they are only 120 miles away from me. But I have a cousin in north carolina who said they shipped to his door within 2 days. Ymmv
Prices are very good on the hifi type electrolytic and his opamps are hit and miss price wise but its worth it for me to support a local diy company.
