Yes indeed - that's a fairly high level model, only really bettered when you jump up to Nikons costing £600 second hand. It should be perfectly adequate.
There aren't any 7600i types on ebay at the moment but there are a couple of the older 7200i models which are pretty good, although only single pass. I think you'll struggle to find them cheap as this is a popular time of year to start this sort of project so they're quite in demand.
Be very careful about the exact bits at the end of the name (i, SE etc) as it can make a large difference to the functionality or software. The Plustek website describes the differences. The SE versions have slightly crippled Silverfast software for instance.

Some people don't like the included Silverfast software so have a look at Vuescan to see if you prefer it. You can download a free trial:
