Where is good for kitchens these days?

Hi forum,

I'm planning on re-doing my utility room - so want some kitchen cabinets for ditty / self build. I'm ideally after tall wall cabinets, and a couple of base units (inc. one corner one).

Had a quick look at diykitchens (after reading a thread on here), but they seem to not do tall wall units, only the normal ones. IKEA have a weird "only 600 and 400 width" rule, but I need either a 500 or 300 to fit the wall properly.

Any clues? It's just a utility room, so I'm not after PH Royal directors box quality, just decent enough...

Cheers guys!
