Bought one of these today and i have to say they are a kitchen fitter/carpenters dream.
This is the best circular saw i have ever seen.
Use it with the guide rail and produce splinter free dead straight cuts in all kinds of materials with no real effort at all.
Great for sink cutouts and other worktop cuts.
Only downside is the price....£380.00 with guide and kitbox eeeeek but a truly professional tool with a 3 year guarantee.
Not so sure id buy one just for DIY though.
See one here on ebay
