S.B.
We had a Little Tyke set for a while. I would advise against that set. It was great for a while and I liked that it was light and easily moved (I could take it outside for messier projects), but it is NOT meant for tall kids. We outgrew it quickly.
We find an amazing set at a garage sale. And I have seen some terrific ones on sale on craigslist. So I would suggest checking there if you are comfortable shopping there.
I know several people who really like a few of the sets offered by Ikea. My SIL has two rather tall children and she has loved this set http://www.ikea.com/us/en/catalog/products/80153701/?quer.... They have used it for a few years. She bought the table that matches. And I know many families who have this set http://www.ikea.com/us/en/catalog/products/20099496/ Seems to do really well, but you may not like that it only comes in bright colors.
