spanish clases (Panama City)

Hi folks,

I'm new in town (2 weeks almost) and as I'm planning to stay longer I need to improve my Spanish drastically. The thing is now I haven't got a clue about prices and quality of school here and I don't wanna get ripped off. My boss suggested me a german guy who costs $8/h but as I'm from Germany myself I'd rather have a native speaker. Another colleague recommended me a school called EPA but to classify my level of Spanish they sent me a formulare to fill out. So I'm a bit sceptical about that as well.

I hope someone here has a good recommendation for me.

Cheers,
Claudio
