Best diagnostics equipment for amateur use at a sensible price

[sew]

I currently have Peake R5-FCX-3 diagonistics tool, and also Carsoft software.

The Peake tool works fine with my 2000 E53 and our 2002 E46s, but is limited to DME diagnosis and isn't exactly user-friendly.

The Carsoft software will read pretty much all modules on the 2000 E53 via the BMW-proprietary "DLC" socket under the bonnet, except for the DME & EGS which need to be read from the ODB2 socket inside. On the 2002 E46s which just have ODB2 it will just read DME, and I have to use my Peake tool on these to reset the Oil and Inspection (IC module) on the E46s!

So I have no way of reading anything apart from DME/EGS on anything without the BMW DLC socket, which is basically anything after year 2000. I'd like to be able to read all modules (with normal resets, etc. possible) for any year up to around 2005. I don't mind if it's a dedicated hardware unit or software. I already have the DLC & ODB2 connectors and serial cables for the Carsoft software, not sure if these would be compatible with other (better) software?

Can anyone come up with any ideas/suggestions, bearing in mind that I'm not made of money!?

Thanks.
