It depends what your ultimate goal is? Just for play/learning etc or other?

Complex service OLT is going to be $2-3k at least on eBay.

The thing is though GPON is not very vendor inter-operable. There are

There are also SFP modules that have integrated OLT’s that I have heard of
people using with Cisco routers with third party ONT.
 Not sure on cost though.

If you want to learn you could pick a particular vendor and see if they
have training. Cisco, Calix, Adtran, Nokia etc may have training material
and have the ability to do labs.
