I was looking around for an uprated starter to add some zing to my ignition..

There's not a lot of info out there except to Ebay sh*t and 2k starters with 14 teeth? Price-wise I've seen 40 quid all the way up to 200 quid. Of course, money doesn't always equate to better performance / quality.
Any thoughts / advice? What are you lot using?
Thanks in advance!
