Quick decision on brushless esc needed!

[dobber]

Ive got to order today as im on holiday as from tomorrow morning, coming back on Thursday next week and racing in the SHRCCC fastrax event. After buying a second hand esc off here which has been nothing short of £60 down the drain!!! Im forced to get a new one, but I have to order today to get it for next Thursday when I return.

Do I go for

Or
http://www.m-k-racing.com/product_info.php?products_id=8223 I know one person to have problems but many others havnt?
Or
What else around the £130 max price. I need to make sure its here for the end of next week.
Oh the dilemma!!!!
