Epson pro 4800 vs pro 3800

I use now a Pro 3800, the switching between MB and FB dosn't work.

So i want to make an upgrade to an newer printer.

I can buy a second hand Epson pro 4800 for a reasonable price.

I read a lot about clogging heads on the 4000-4800-4880-serie of epson.

Is the 4800 more sensityve for headcloggings than the 3800?

I think that the printquality is the same for the 2 printers.

Ho have experiance on these 2 printers?

Or mayby it is best that i buy a new 3880 ?

(the price for a new 3880 here in Europe is 1100€, this is more than in the states)
