For $$ I'd say Alex.  For over $$, I'd say April at $$$.  If you want under $$, that kind of tough to find anything beyond the basics.

I usually only see under $$ gals my best of under is Kelly/coni very into it!, Brandy very passionate, Cassie a great time, Heather shadows of intimacy quite attractive and very fun, Alex @ $$ is awesome

Over $$ Tuesdae & Misty...under Britney, Kari & Heather

Would have to say three wonderful women come to mind.....Coni/Kelly, Brandy, and Alex.  All provide a great value and love what they do...never been disappointed by them.
