At this age they do not play with much. My 14 month old plays with socks, shoes, toilet paper rolls, boxes, nesting cups and measuring cups (taken from my kitchen cabinets), along with blocks, & her ride-on truck. In addition, she loves to empty the indoor play kitchen, but does not play with any of food, just makes a mess. If he does not have blocks or a "ride-on" car or truck, then look into one of those.
As for playstands (we never had any) but all my kids were climbers. So I am not sure if you want to waste a lot of your energy keeping him from using it as a ladder.
Also when you get a chance, go ahead and buy some "rock crayons" but nothing else. He may start using them around 18 months, if you use them with him. All of my kids used them at an early age, if fact my 14 month old is trying to use them now since she is watching her older sisters. The rock crayons are nice since they do not roll off the table.
Also you may not want to spend a lot of money on an outdoor kitchen. We went to a garage sale and picked up a real set of pots and pans (they are kind of large for a 1 year old but my 14 month old still bangs the lids together and puts rocks and stuff in them), cookie cutters, measuring spoons and measuring cups for an outdoor kitchen for cheap. For counter space, we placed a board over some tree stumps (we had a large tree taken down a couple of years ago). My kids love the set up and it gets extremely dirty with all the mud, weeds, sand, crabapples, etc. For an outdoor water table (or sand table) you could use a shallow Rubbermaid storage container that you can buy for under $10 and place it on a milk crate instead of the more expensive Step 2 or Little Tikes brand. All my kids love the water table and sand table even the 14 month old. Just do not place them next to each other since the water table could get real icky from the sand. We have them on the opposite sides of the yard.
Instead I would spend my money on items that will last for many years of play such as indoor play kitchen, wooden animals/figures, wooden cars, wooden trains, and wooden or knitted play food. However do not buy too much since you do not know what his interests will be when he gets older. So if you could afford a variety maybe (2) wooden animals (look at Jalu), (1) wooden car (Palumba has some reasonably priced), and a few pieces of food (also at Palumba) like an apple, knitted cheese sandwich, eggs,& a couple of plates. By two years of age my oldest was really into the play food. My second child really liked the wooden animals and cars by the age of two. My third ????? At two my nephew was really into trains, while my cousin’s son loved garbage and construction trucks. It is not like they only play with one thing, but you may not want to spend a lot of money on things such as an indoor play kitchen that may not get played with.
