GAHH top installation cost in MD

[lejolierogue]

Dear Enthusiasts,

So I decided to replace my top with the GAHH convertible top w/glass - sonnendeck canvas for $820 bucks.

Thing is, the installers that they recommended in the MD area (Baltimore vicinity) have all quoted me $900 - $1,250 for installation.

Does this figure sound right? Looking at some other threads, GAHH does the install for like $600 (saw one thread where GAHH top installed for $1500).

Your thoughts?

Thanks in advance.
