Wood ILF- Lark in any length. figure out a way to keep the LLA from vibrating loose, and put in longer screws, for <$200 hard to beat. Not cut far past center if that matters to you. I inlet mine another few mm.
Used ILF.. Just about any decent brand is good.
I have also used a couple Mybo and been pretty impressed with them for quality. I set up a beginner rig with one recently, and own one myself in 27".
To be fair: just about every riser I have ever purchased shot "good enough" for me. I do notice fit and finish are sometimes lacking, and once or twice have needed to run a tap through riser holes to clear threads of paint, or file down something. But so far they have all shot fine for my relatively lightweight limbs at ~30-33# on fingers. I am starting to buy some of the cheaper ones now ($100-$125) to see if that holds down the line. I got a 21" recently I have not yet shot that is a bit clunky in appearance, but appears to have good fit and finish, and Steve is sending me a 19" Tbow Tempest clone to play with. Will see how far I can push my uukha XL limbs before I get annoyed by stacking
I had one experience that bugged me, seems to me a severe quality issue: I bought a REALLY cheap 17" Nikka with 12 or 14# ILF limbs almost a decade ago for my girl, if I recall for ~$130 as package. Nikka did not sink the limb adjustment plate deep enough in riser, so the limbs were resting on the ILF bolt vs. on the riser pocket. Fixable.. but annoying. I saw a fellow at our range with same riser, same issue. Simplest fix is to put a little spacer plate in limb pocket so limb bottoms out. Lesson: put your bow together and look it over carefully, see if limbs really fitting properly. I missed it for a while.
