I think that for the money, ease of use, functions etc the ETB Digidash is very hard to beat.
I did consider it, but I couldn't quite get away with the aesthetics and ended up spending way more on the AIM MXS Strada - but of course, personal taste is just that - personal.
The AIM dash is superb - but certainly not 'easy'. It still has a few minor layout gripes, but it is is so configurable and updatable that it won't be long before that is sorted (if not, then I'll sort it when I can find time to hack into it again). The ability (for me) to actually get into the software config files and manually tweak them to suit my own needs is a huge bonus - so personally, right now, this dash simply can not be beaten. It also has a CAN interface for my ECU, lots of add ons (if somewhat pricey) and to top it all - looks really, really nice.
