scanner dilemma

I've just started shooting film again.

I started with an ancient Leica and, in a moment of weakness, ordered an RZ outfit on ebay (should arrive any day!).

Last week I purchased a Plustek 7600 from B&H - it seems to do a good job BUT is, of course, limited to 35mm.

I -have- an Epson Perfection 3200, which I've used in the past for 4x5 and medium format.

So here's the dilemma:

Should I return the Plustek (I think they'll take it back) and get a V700? (and ditch the 3200 on ebay)

OR

Should I keep get a betterscanning ANR holder for the 3200 and call it good?

I'm using VueScan for both - if that helps.

Thanks!
