Welcome to the dark side, life will never be the same... That being said there are a lot of option out there, you can find many under 70 that are great. I generally try to keep my min under $100 US when possible. Try V-coins a lot of options there, MA-shops is pretty good too, but better for medieval (my fav area) or numisbid. The best thing you can do is read a lot and do a lot of window shopping to get an idea of what things are going for.
