We have a 2045, 2060, and 6060 and while I haven't compared them to a 5000, they do give a glossy look as you would expect off of a fuser oil based machine, as stated previously...IMHO they look better in THIS ASPECT than the "matte" oil-less newer machines like the 700.
I will also say that if you have to print on 300gsm paper then the 6060 is spec'd to run up to 300gsm, whereas the 2045 and 2060 are only spec'd to do up to 280gsm. You should be able to find a secondhand 6060 relatively cheap, we did about 2 years ago. In addition a 6060 is less time consuming to maintain on the user-end, with user replaceable/cleanable corotrons and fuser webs, as well as much less drum problems (I still do a lot of this type of maintenance on the 2045/2060, but unless the techs authorize it they won't let you do this and its a slight pain and time-sucker versus the 6060). We have run up to 120# cover weights on all 3 machines and the 6060 usually will give you decent quality on this kind of stock, though keep in mind that you start to run into trail-edge deletions so you can't push the image size spec too hard with heavy coverage. The 2045/2060 will run 300gsm paper in the sense that you can usually make it feed it and it will come out the end of the machine...but it is not always sellable quality unless its really low coverage. Sometimes I've had to fudge the paper settings to make it look better but I wouldn't recommend it if that's all you plan on running, as you will experience a lot of downtime/quality issues if you buy a 2060 and that's all you use it for.
Me personally, I think given your intended application the 6060 is a better buy, not to mention buying into a slightly newer/more reliable platform. I'm not sure what the price difference is between a 2060 and 6060, but I think its safe to say that its probably worth the extra money to actually have Xerox support you when you run 300gsm paper than to have to "fudge" the 2060 and go through fusers constantly and be down all the time...not to mention to being up more frequently just in terms of user maintenance...the 2045/2060 are very sensitive to temperature/humidity level changes in an environment so you have to clean/replace the corotrons relatively frequently dependant on the seasons/climate of your area.
