I'd suggest looking into the "Black Hunter" recurve or longbow. They can be had under $100, are available on Amazon and Ebay as well as other archery shops but are usually re-branded at a higher price.
They're glass back/belly and a bamboo core and shoot very nice.
I believe there are some knock offs out there but if you stick with the Obert, Mandrin Duck, Glurak and various others (you'll have to do some research here) you'll probably get a good one.
I'd suggest making sure the riser and limbs match up if ordering extra limbs because there's a squared off limb design vs. a tapered limb design where they bolt up to the riser. Both will fit and doesn't effect performance just esthetics.
The recurve vs the longbow perform about the same due to the thinner profile of the limbs on the longbow.
There are reviews all over doing a quick Google search and several videos on YouTube of this bow.
