I couldn't find any for that price. you got any links?Is it worth building your own when you can get fully working jamma cabs for £250 or less in the UK?
Where are you based in the uk?
Maybe it's a better idea to get someone else to maintain / operate the games if you are this unsure?
There are people with old machines ready to put them on location and maintain them for the profit share.
I would rather understand the basics and try and put one together so if anything goes wrong I got any idea what to do to fix it but yeah it's an option.
Thanks
