I have a Plustek 7500i (which came with Silverfast SE Plus, no longer usable with current MacOS) and an Epson V500 (boxed away on a shelf somewhere). I much prefer using the Plustek for 135; the film holder is much better for a start (though if you were taking half frame or XPan or Lomo you wouldn't want the Plustek film holders as the are very much 24*36mm). The Plustek is also capable of multi-scans as its registration on multiple passes is better. This is used by Vuescan (and SF) for multi-exposure as well as multi-scan. Multiscan reduces noise and somehow improves scan quality by combining several passes; I will normally do 2 passes but for frames that look really promising I might do 4 or more. The multi-exposure adds a slower pass that blasts more light through; it helps with shadow areas in reversal film, or highlight areas (eg clouds) in negative film. The other capability in those Plusteks that have it (designated with an i) is the additional infrared scan used for dust and scratch removal. This can't be used with black and white film (except XP2) or Kodachrome, but can be useful for C41 and E6, specially older slides that have been sat around for a few years. It's not perfect, and can introduce artefacts, but it can also be a big help.
Have a look at the reviews on filmscanner.info; the Plustek models tend to be software variants on the same hardware, so if you don't see the exact model name have a look at something similar.
I will scan "ordinary" frames at 2400 ppi which gives about a 8.5 Mp image, and ones I think are special at 3600 ppi which gives a nearly 20 Mp image. There's not really that amount of image information in either scan, but you can certainly print to A4 at 2400 and A3 at 3600.
