That's a good question. As far as I know, there isn't anyone out there still selling complete replicas of those two bots. Due to the rarity of the parts (Gypsy's car seat, Cambot's fruit bowl), it's pretty much become the realm of individuals finding all the bits and building them themselves.
That said, it's always possible to find the parts yourself and then, if you're not comfortable building the bots on your own, send the parts to another builder who can build them for you! I'm sure there would be a forum member or two here on this site that'd be willing to offer their expertise! My best advice is to keep watch on eBay for the parts you need, and once you have them, maybe see if someone here is willing to help you put the pieces together!
This buy/sell/trade page is also an excellent place to monitor for rare parts popping up online, so bookmark it just in case one of the parts you're looking for shows up!
I hope this helps! Good luck on your bot building quest!
