I have the Plustek and love it
Although I can't make any comparison to your scanner, never had it or seen a scan from it, I can tell you the (test) prints I've made with the Plustek so far look really good. The reflecta Proscan 7200 should deliver the same quality, but with faster scanning times. In the US reflecta is sold as Pacific Image I believe.
I have no experience with scanning and have absolutely no idea what I'm doing, so I assume they can only improve if you have more knowledge. I just adjust the prescan till it looks about right. I find slide films scans best, followed by negative. B&W is more difficult for me, I read somewhere that it needs to be treated differently when scanning, but haven't practiced this yet.
The prints I've made so far are from ISO 100 and 400 slides and they look great up to A3 and A2. Everybody has their own tolerance for grain, I find even the ISO 400 ones acceptable at A2. In A3 there is almost no grain, only if you put your nose to the print there is some. But this is according to my standards, you would have to see it yourself. The scans show more grain on screen than in print.
Downsides: manual feeding and loading of the film. There are also options for multiple pass scanning and scratch/dust removal, which make scanning times quite long.
If you would like to see some of the test scans I made let me know. I posted some on my flickr account for someone else, but I'd have to add you as a contact and a family member, because I don't want the images to show im my stream, they're just test shots.
Cheers,
Daniel
