If anyone is still following this, I ended up getting a HandySitt...I LOVE LOVE LOVE it. For some reason, the past two weekends (only) on Amazon, they were discounted as much as 50%!!!!!! I got the beech with brushed stainless for $62! It retails for $99 (it is a premium finish due to the stainless), $10 more than the standard HandySitt chairs. I ended up getting a seatpad and the "standalone" attachment as well.
I love it so much. I would recommend it for a standard highchair, for those of you who don't want to buy a high chair and then a booster. As long as you child can sit up well, it will work (manufacturer recommends use from age 7 months and up...I think this is reasonable). It can be used all the way to age 4 1/2, per the manufacturer, and I believe that as well.
It is ultra modern looking, beautiful, elegant Scandinavian design, and made in Denmark. My 15 mo loves it. I wish I'd known about it 2 1/2 years ago when my older daughter was just going into the high chair.
Here is link to the black with beech...but they aren't on sale anymore...check back on Amazon...it may happen again
