We loved our walker!!!
Actually, I don't worry as much about a brand - but it would be great help if you could take your lo with you when picking one out. Also, check out 2nd hand shops or used baby item shops. These are generally only used for a few months, so you can get great walkers 2nd hand for next to nothing!!
Back to the poitn - the reason I say take your lo with you is that we had a total of 3 walkers, and one of them had to have been made for a freakishly tall child!!
My kid has always been off the charts big, and he could barely touch the floor to move!! AND - here's the best part - it didn't adjust!!!
So make sure it fits, and/or adjusts and fits your lo, that they're comfortable, and it is as sturdy as can be...then go for it!!!
