Apple doesn’t make DVI adapter for my 23” display?

i'm looking at the new mini as it's suitable for my needs, but was told in the apple store my 23” apple HD display
(the older all aluminum one - not the new one with the black boarder) could not be connected because
apple doesn't make these adapters anymore?

The guy at the store did find me a used 'Apple DVI to ADC Apdater Display Power Cable A1006' on eBay
but it’s got a honkin big power supply bar and I was told I’d then have to buy another adapter to connect to it
if I wanted to connect it to the new mini

I find it hard to believe that a perfectly good monitor can't easily be connected to the new mini???

i want less cables not more

any thoughts, advice?

thanks guys

i'll take a picture of my display and the connection and head back to the store
