I think the best idea is to try s/ware, to see how it meshes with your CAD, with your requirements, with your experience and support.
Try the free s/ware (as greg posted above) ... but don't have high expectations (you get what you pay for). Maybe tehy'll work out well for you. I'd spend a lot of time verifying that the output of the FEM is "correct" (and that it is not a random number generator).
Try talking to the major players (including SolidWorks), talk to the distributors ... they may be able to set up a licensing agreement that better fits your budget. Maybe you only need a license for a short period (during design phase ?) rather than a 12 month commitment. The distributors want to get clients, and they don't like potential clients going over to the opposition.
