Hey, uh, so... Strap ons? (NSFW)

I did a search on this sub and didn't find a great deal about strap ons, so I hope this isn't something that's asked alot. Aaaaanyway, my boyfriend and I (trans girl) are looking to switch things up a little bit. I'm starting to find I prefer not to use my penis during sex and I think he sometimes feels inadequate because he can't fuck me in the way a cis guy would. So, I'm thinking about strap-ons. For you guys that use strap ons, what is your favorite? I'd prefer to buy a harness and dildo combo, I think him and I would prefer something realistic (instead of a blue or purple dildo. Veins, balls, glans, the whole 9 yards). I don't have too much money to spend (I looked at the Vixskin dildos, and $80 is too much for a dildo at the moment) and if I could get it on Amazon, that'd be great. Sorry if I'm breaking any rules here! Thanks guys :)

Ninja Edit: Are things like feeldoes easy to keep in? I'm open to the idea of using one, so that's totally fine to suggest any good ones, but I'll have to talk with him about what he's comfortable using.
