ISO UV Gel Documentation for System for Small Biology Dept.

I was asked to find a small gel documentation system for our biology program. It will mostly be used by undergraduates, occasionally faculty, to document Ethidium Stained Gels. Price is the main issue, but other factors like overall sturdiness can be considered as well because we will be having students using it. The current option my colleague is looking at will cost about $4,000 so I'm hoping to find a less expensive option. It's been many years since I have done this type of work so I'm a bit in the dark about what we should be considering.

All advice is appreciated. Many thanks.
