Hey bud. I've been using a 7400 for the past 8 or 9 years, I havent't fully converted to digital yet and so it gets a lot of use. Any dedicated 35mm plustek scanner comes highly reccomended by me, they're capable of such high quality scans. Of course though, the quality has to be there in the slide first and it helps to know your way around Lightroom as the scan is likely to require a little adjusting if you want the colurs perfect. The Silverfast scan software which comes with the scanner has some colour presets but they're crap and there are some manual tools for adjusting levels, curves and basic colour correction but nothing beets pro software like Lightroom or Photoshop. The pull & push tool is quite handy, pre scan the frame for a preview and you can use a slider to either pull or push the exposure so that when you hit the scan button to do a full res scan, you have perfect exposure. Handy for pulling out more detail from a shot thats a bit over or under exposed. Also, I normally scan with the contrast set to rock bottom, that way the image that's saved (I always reccoment .tiff format) is nice and flat and so the coulers are easier to correct in LR and some proper contrast can be introduced.
Here's a typical example of a scan...

I've just joined Instagram and I'm in the process of uploading some of my favorite photos, look for @36_frmes_later if you'd like to see more scans
Also, if you do end up getting a Plustek scanner, I'd be happy to jump on a Skype screen share with you to show you how to get the best out of it
