If you buy a flatbed scanner, the Epson V700 is the only reasonable option. The v700 is a considerably better scanner than the 4490. The V700 is comparable to a dedicated scanner...it really is...IF you buy the Doug Fisher holder with the glass AND you prepare to spend considerable time calibrating your scans every time you use the scanner. Just prepare for spending 20 minutes getting things at the right height every time you scan. Unless you devise a way of locking the height screws...
In a dedicated scanner, I use the Multi Pro by Konica Minolta and it's marvelous. The 9000ED is HUGE and not as highly reviewed, but it is possible to buy it new still (multi pro has been off the market for a long time).
Go here to see my own comparison of a flatbed (v700) and a dedicated (multi pro) :
