I got a cheap Eur55 bench model from Lidl as a temporary measure when I could only find 3ph floor models here. I've bought it on the basis that it will always be useful even if I subsequently buy a floor one and was cheap enough not to matter.
Bob's point about being able to swing the head around for longer stuff is valid. The more limiting feature is that the distance between the column and the chuck is occasionally not enough. However, for the price it has been great and done 99% of what I need it for.
Taking the time to make a long auxilliary table with a fence with adjustable stop and fitting an LED light and a depth gauge was very worthwhile. Neither bench top nor floor models are normally designed for woodwork and making a proper woodworking table for either is pretty much a must, whichever you buy.

I was always a buy the best you can afford man until I had to replace my British workshop when it was burgled. Cost considerations made me examine a lot of cheaper stuff rather than just going out getting Starrett et al. I was surprised to discover that a lot of cheaper stuff isn't necessarily junk and that a lot of dearer stuff is not what it should be for the price.
1. Will it do the job?
2. Will it do it as well as something dearer?
3. Will it do the job as well as something dearer if I made some modest modification?*
4. Is it accurate enough?
5. Would two cheap ones be more useful than one at double the price? (Different thinking but would two cheap routers enabling two different bits for quick swapping over be more useful NOW than one expensive one that I'll still have in 30yrs?
*When the Taiwanese horizontal bandsaws first came out they were way cheaper than the heavy industrial models that were the only other possibility. The stands were flimsy and the vices not much better, but fundamentally the thing worked. Articles in the HSM press soon had us all knocking up better stands and sorting out vices, switches and bearings, all for little money, creating something worthwhile, especially when most of us had been using manual hacksaws before. We soon got used to regarding the early Taiwanese stuff as reasonably priced kits of parts, that when fettled up, gave us previously quite unaffordable machine tools.
