although I wouldn't call this "great" it worked really well for our twins:

Pluses:
-compact,
-easy to clean,
-portable-easy to bring along to grandparent's house, etc.
-doesn't take up much space (we attached them to folding chairs),
-versatile (used them reclined w/out tray when our kids first started solids, then used them upright with tray as a highchair, and then when they were ready to eat at the 'big table' we took the trays off and just slid them up to the table - much easier to do than with a regular high chair.
-fairly inexpensive (I think I paid about $20/each for them and considering we used them almost every day for about 3 years, it was quite a deal IMHO)
Minuses:
-recline mechanism is a bit 'sticky' (not an issue for us since we rarely switched between upright and reclined setting
-has only a 3-pt harness so if you have a super-active little one you might want something a bit sturdier
