Opinions on Best Buy for installation?

[PrivatePixel]

I'm looking to replace the JVC Arsenal head unit installed a couple of years ago with this:

JVC KD-HDR50


Here's my dilemma:
Crutchfield (where I purchased the Arsenal receiver originally) has discontinued the pictured unit from its inventory a few weeks ago (I have seen the 2010 models shown at CES, but I prefer the aesthetics from 2009). Amazon sells it for less, but they don't include a mounting kit, harnesses, etc. Other e-tailers show this as backordered and don't include any accessories for installation.

Best Buy carries this model currently for ~$160 and they offer installation. Bottom line is: can I trust them to do a decent job? Assuming that my last installer did a half-decent job when he installed the Arsenal unit, I plan to reuse the existing accessories (mounting kit, etc.) for this install.

I wasn't too happy with my InstallerNet experience, so I'm keeping my options open.
