Hello everybody!!!! i ggot an 87 astro van, i NEED rims...i was looking into 22"s in chrome. or 20's.........

What i need help with is FINDING THE RIGHT ONE, ive seen about a million rims on navigators, escalades, etc. but when i imagine them on my astro, they just dont look good, heres a pic of what it basically looks like (but its got paint now... http://www.1987astro.8m.com/theastro11.jpg )...PLEASE HELP ME, im lost...any help is very appreciated. and dont flame me. please

EDIT: or you could just tell me what kind of styles would look good, as opposed to a specific rim.

and the budget is about 4-5k...i will spend more if i think i need to :):):):)
