Well, I can't do your shopping for you. Here are some Google results that will keep you busy comparing sizes and prices:
End Grain Butcher Block Cutting Boards
Butcher Block Cutting Boards
Note: the term "butcher block" is not synonymous with "end grain" anymore ... it just means pieces of wood glued together (end, side or edge ... or some combination) - you have to look at the board and the specs. Some boards use a mixture of end and edge grain in alternating bands for "decorative" purposes.
Boards with legs are not reversable (you can't use both sides).
All of the true Asian cutting boards I have seen are round slices of a tree trunk (end grain) but they are not often seen in the US unless "homemade" or you have a good Asian market in your area. They are the most prone to splitting and require the most attention to maintain in "pristine" condition ... but they are generally the cheapest.
People who have switched over to bamboo boards are fanatical about them - like ex-smokers believing second-hand smoke contains more Carbon-Monixide than the smoker ingests. They are generally pretty, durable and all that I have ever seen were of very good quality ... and due to the nature of bamboo "may" not be as prone to splitting and warping as hardwood boards if not properly maintained.
