Randy there's a few threads about this already, but anyway we went with Robeplan, they did a great job, took a good 5 hours (if memory serves me correctly) and were very neat. We got the semi ones, can't remember the right name but basically we didn't get a back on ours i.e. you can see the wall of the bedroom that they're on. This suited us as a) it was cheaper and b) we can still use the double socket on that well (i use it for my hairdryer which I then keep in the wardrobe). I think they're great, we get all of our clothes into them, and drawers for socks etc. Also there's a bit at the top for storing luggage etc. Ours are mirrored and really look good in the room.
Only things I'd say is I should have got a wider 'long' section (for coats/dresses) it's not big enough and the piping they put at the edge of the wardrobes has come away a bit (we have to keep sticking it back into place). Only small things though - think Sliderobes might be slightly better quality but we were happy with Robeplan for what we needed.
