Hey man,
I'll add my 2 cents for Hobbywing...they make great esc's (they also make Orion's esc's, passion's, some HBI's, etc...).
The new V3 is over priced (I bought one though) but it's great on the features side.
You can get a V2.1 120A for a bit over $100 now...I just picked up one of their motors (will use for 2WD buggy) which is sensored...we'll see how that works.
The brushless hobbies I cannot speak of...their programmers and even the units themselves look like knock-offs of others but perhaps Mantis is correct...
Thanks for the insight, but the honest truth I'm done with hobbywing/gens ace items due to hobbypartz terrible customer service...... I actually owned a few hobbywing esc's from their xerun 60a to 120a and I personally didn't like them. I mainly run tekin now (best customer service out there IMO) and have had "0" issue's with any of their products I own, and the only reason why I'm not putting a tekin setup on my backup sc10 is I just want to try something different out and want something cheap. I mean you can't beat 57 bucks for a 120a esc......BTW I just ordered two of them, I hear they go out of stock pretty fast and can take some time to restock at times......
