"Sanwa prices"? Any worthwhile servo for 1/12th scale is going to run you over $100. The defacto standard today is the Sanwa PGS-HR because it is small, light, fast, precise and has reliable centering. The topper to all of that is most 1/12th scale chassis today are built around this servo. If you don't go PGS-HR, your next best bets are the Xpert MI-3301 or KO Propo RSx3-12. It looks as though you run Xray and Awesomatix chassis - both premium brands, so you understand the value, even in premium-priced products. Spend the extra $50 and get a servo that you aren't going to want to replace after your first few races.
