Good call on measuring my door! I never would of thought of that. What's the average price on cabinet's you've bought?
I don't - we build them.

Obviously I trawl ebay frequently as I list on there myself periodically and some customers have ordered controls to fit into their cabinets they are MAME converting. Here's what I see frequently:
- Generic 2-player JAMMA cabinet - £50-£100 (empty or with controls only), £100-£200 (unfinished projects with a monitor, controls and maybe an unfinished PC), £200-£400 (Fully converted for MAME with new artwork, custom control panel etc. and a working PC)
- Proper custom MAME cabinets - £300-£600 (larger custom shells with more controls, up to 'project' standards you see on BYOAC)
- Genuine arcade machines - £50-£100 (empty shells in average condition), £100-£300 (complete cabinets (non-classic, average condition), £300-£1500 ((classics in better condition), £500-£1500 ('simulation' type cabs like racers/skiing/DDR/etc.)
