Baltan was in the first wave and I think you can still find sets of that on Mandarake for decent prices.

Buyer assurance on Aliexpress comes in the form of Alipay holding your payment as an escrow like how Paypal does on Ebay, though it is limited to a 120 day(?) guarantee period and their platform CS usually don't intervene in disputes until the very end of this period.
As mentioned in my previous post, China's ongoing delivery jam is the bigger concern right now. You might want to check with the seller first, ask if they are able to ship.
