8x8 chassis under-guts... anyone tried this?

[WhiteWolf McBride]

I saw the name mentioned, so I looked it up: RCMIN /RCBRMIN.

Looked through their site, and noted their 8x8 axle combination as a possibility: http://www.rcbrmin.com/8×8-drive-me...ock-p-508.html => List Price: $448.78 USD (plus shipping)

Compared to $360.00 'undiscounted' price for the Integy 8x8 axle set, how does the RCBRMin set compare for fit and quality to the integy's? Ease of mounting to Tamiya chassis? Other comments? (noted the cable-actuated diff-lockers... good/bad?

Just asking, as it seems to be the nearest competitor...
