I don't think you will run into trouble with the non-thunderbolt monitor or the 2010 Mac Mini not being supported anytime soon. Keep in mind that plenty of Mac users (including my daughter) use commercial, non-Apple monitors (hers is by Samsung) via a miniDisplay-to-DVI adaptor (there are also miniDisplay-to-VGA adaptors and other types as well) and a ordinary DVI cable. These PC-type monitors work fine with 10.6, 10.7, 10.8 etc. I don't see any issue with these or your pre-thunderbolt Apple display working well into the future. They all use standard interfaces.
My only reservation would be with the "refurbished" unit. That means it probably broke in the past for someone. So make sure it comes with some sort of warranty. You might look into "regular" monitors made by Samsung, etc. Some of them are really high quality, such as the one used by my image-fussy photographer daughter. They only cost about $100.

Thank you steve626 for the advice. I am definitely going to go for a less expensive monitor. This will solve any worries I have about peripherals for the time being, and since I need one right away, I can make more involved decisions later.
I am also glad that you think my 2010 Mac Mini will still be supported for a while.
