I got my kids a paint station each for Christmas. I found this product in a Polish online store called HobbyZone, and both delivery time and packaging was really top notch.
The MDF kit is quite easy to assemble - although I thought I would have to bend the curved pieces a bit into shape before glueing, which was NOT a good idea (as you can see on the station furthest away).
Apart from the frame, the kit is made of a laminated light-weight kind of MDF, and I think it has a tiny tad too low density, but only time and wear will tell if I am wrong or right.
The paint station (the smallest type) comes at only about €16, and if it proves to be sufficiently sturdy for my kids to use, it will have been worth every penny.
