Spring compressor buying tip?

[benhogan]

I've decided to take the plunge and buy my own spring compressor. There seems to be just 2 prices. $169 or $500. Will the cheaper one pretty much do the trick? Obviously, it will not be a tool that will be used often so it should be fine, right?

I need to redo all the front end rubber on the w123. The cost of paying someone to do it is a multiple of the cost of the parts and the spring compressor.
