Driver Review: Microflex Drive vs O-like vs RKCSTR vs LM317

Would anyone do an comparison review on microflex drive vs O-like, red and blue, RKCSTR, and lm317 driver kits?

Price? complexity? market popularity? quality?

I will be making one up in about one week. I have never worked with the O-Like driver before however, so I would have to exclude those. The comparison will include a simple chart or two, and then a few how- to tips on using them. Think you can wait till then?

Yea that'll be fine. I really impatience, but i'd prefer the quality review.

Thank you
