I just finished my SCJP training at this place www.sharpdevelopment.co.uk (for those in London) I remember first seeing this link here at javaranch. Thanks to whoever posted it, sorry I cant remember who it was. The training was certianly worth it for a reasonable price. Good for people like me who need to be pushed a bit to focus on getting certified.
I am now SCJP 5 certified. They do the SCWCD as well. I might be going for that too after a while. Anyone cares to join me for that? I think they're running another SCJP batch too this month.
