I would also recommend steering clear of wireless computers, they might look like a good idea initially but in practice unless you are willing to go for an expensive model they tend to be unreliable.
As for setting up the only difference is that you have to wind a wire around the the front fork and then up the brake cable, as Keith says.
I would recommend the
VDO C4. VDO are instrument makers, unlike some other makers and so understand making accurate distance and speed measurements (they also make speedometer for the likes of Mercedes and BMW).
I am sure there will be others along to soon to recommend they favourite bands.
