Opinions on the 620 board

First off let me say you guys have made my first few days here awesome, everyone has been very helpful & I thank you.

My excalibur vibrating board hasn't arrived yet, but I already feel as though I didn't make the wisest choice in boards. I noticed miggle has a special running on their 620 board, & was wondering what the general consensus is for the this board?

I love the custom boards that i've seen & wondered if they're compatible with the 620's?

I'm certainly gonna try the vibrating board when it arrives later this week, but may make a switch.
