K20D
DA* 16-50mm f/2.8
DA* 50–135mm f/2.8 : €2,000
DA* 300mm f/4 : €1,000
DA* 55mm f/1.4 : €500
TOTAL : €3,500
Just for fun I thought "Hmmm... what if someone insisted on full-frame and wanted to build the same kit in the Nikon system?" Here's what you'd need, assuming matching FOV (no, let's not have that debate again). All prices from the same vendor.
Nikon D3 (only 12.1 MP but close enough) : €4,200
Nikkor 24-70mm f/2.8G ED AF-S N (not VR) : €1,700
Nikkor 70-200mm f/2.8G ED-IF AF-S VR : €1,870
Nikkor 500mm f/4G ED-IF AF-S VR N : €8,500
Nikkor 85/1.4 AF D IF (not sealed, not VR) : €1,100
TOTAL : €17,370
Of course you could improve on your telephoto speed one stop by getting instead:
Nikkor 400mm f/2.8G ED-IF AF-S VR N : €9,650
Or keep the same speed and improve your reach somewhat:
Nikkor 600mm f/4G ED-IF AF-S VR N : €10,200
Correct me if I'm wrong, but it looks like you can buy five Pentax systems for the price of a single Nikon full-frame system. Is the grass greener? Looks more like a scorched earth policy!
Errr, OK you're wrong, let me correct you...
First off, do you really think the K20 and D3 are comparable cameras? If so, please, try a D3 for 5 minutes...
Furthermore, your list of "equivalent" FF lense is deeply flawed to say the least, let's try this one, from the Canon camp (part of which I own):
K20D ==> 5D: 1699€
DA* 16-50mm f/2.8 ==> 24-105f4L IS: 939€ (equiv. 16-70f2.6)
DA* 50–135mm f/2.8 : €2,300 ==> 70-200f4L IS: 1049€ (equiv. 46-133f2.6)
DA* 300mm f/4 : €1,100 ==> 400f5,6L: 1200€ (equiv. 266f4)
DA* 55mm f/1.4 : €500 ==> 85f1.8: 370€ (equiv. 56f1.2)
TOTAL : €3,900 ==> TOTAL: 5255€
(I took the liberty of taking all the prices from the same online store for the sake of coherence give or take 100€ if you take kits).
So the FF equivalent kit comes up just under 35% more than the K20D kit... hardly 500%!
These setups are the closest you can get from an equivalence point of view and I can guarantee you that the 5D setup stil ends up with some advantages in AF speed and (and that's the most important, at least to me) IQ at all ISO.
More expensive? Yes but not by the margin you stated.
Worth it? For some people it might... for some others no.
