I don't know what you consider reasonably priced, but Newport Brass makes some nice, simple, high-quality wall-mounted faucets. I installed one of these in my master bath remodel this year:
Wall mount faucet
Whatever brand you get, remember two things:
1) Check the specs to make sure you have a high flow rate (at least 5-8 gpm) or your tub will take a long time to fill.
2) Make sure you have a long spout that reaches well over the tub edge: if the spout only barely reaches over the tub edge, you can have splashing outside of the tub if the water stream hits too high up on the inside of the slanted tub wall.
