I too would say that you have the 90/2.5 being offered on account of
the 1:1 extender being offered... unless that is a teleconverter.
Larry's comparison between the 2 lenses may be true, but I have a 6
month-old 90/2.8 and I think that it is an excellent lens. It is
made of plastic, but it is light. If the older version (90/2.5) is
better, it will be very good. BTW the 90/2.8 has a 55mm filter
diameter.
Clear as mud?

Since you mention the 1:1 extender, it is probably the F/2.5 version.
f2.5 = great
f/2.8= not as good

Just been offered a Tamron SP 90mm Macro with 1:1 extender. It's the 55mm
filter ring version. I remember a discussion on the relative merits of the
55mm and the older(?) 49mm version - was the difference in the build
quality only or was there a difference in performance too?
