recurrency
I'm B737 and A320 qual'ed and I use Joe at Alliance (Sim Center) and Dave at Global for my PC's. Great folks to deal with. Been to many of the others and have a cup full of horror stories.
I can also recommend Ray at CPT for the B737, great guy. I think about $4k to $5k for the long recurrent and ground school. You can do yourself a favor by finding a cheap little sim to brush up the scan for a few hours and that will save a few bucks. Some of the schools have an older level B/C sim they will do this with.
Call them for a quote.
