I just want someone to give me $50 to learn the hard way!

One thing the Tekin does have going for it is its size. I have got to admit that the smaller foot print gives you more flexability in where it goes, although pretty much everyone runs the same setup (regardless of ESC) anyway.

On the topic of regulators and the BD's BEC connection... Both of these allow the use of a 7.4 volt lipo which should in theory allow far more options for Rx packs. However I have had very little success finding small lipo packs for this use. SMC had one that was very close to perfect but still a little big. Anyone else managed to find something nice?
