help with motor/esc setup
 

I am building four crackerbox 1/10th scale scratchbuilt boats from Jerry Dunlap plans. I plan on running them with electrifly 600 motors for around $13 each. I need an esc that will provide decent speed, but won't cost a fortune. Here are some options I am looking at. Please let me know what you think. I am open to other suggestions:

1) CEN racing ESC from offshore electric for $20 [link=http://www.offshoreelectrics.com/proddetail.php?prod=cen-esc300]CEN racing esc[/link]

2) Ebay ESC #1 ( looks to be a CEN clone) for $20 [link=http://cgi.ebay.com/50A-100A-Max-Electronic-Speed-Controller-For-Boats_W0QQitemZ260033174518QQihZ016QQcategoryZ3405 8QQrdZ1QQssPageNameZWD1VQQcmdZViewItem]ESC from ebay[/link]

3) Ebay ESC #2 (looks to be a pro boat clone) for $26 [link=http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ih=017&sspagename=STRK%3AME WA%3AIT&viewitem=&item=270100093677&rd=1&rd=1]ebay esc 2[/link]
