This is a pretty good harness and even though I also have a more expensive one I do still use this one quite a bit.
The Tantus harness is capable up to 60" waist and is a good beginner harness: https://www.amazon.com/Tantus-Vibrating-Harness-Dildo-Black/dp/B00GOB8OJS?th=1
You'll want a good quality silicone dildo use. I always recommend the Vixskin dildos as they feel so good. But that would be over your desired price range. But if you want the best experience possible for your first time, you would be best off going for it.
Other than Vixskin, just look for a good silicone with a comfortable size. I would recommend keeping it below 1.5" diameter for your first time.
Oh, Ok, You're just talking about the harness, not the VUL dildo. That's where my confusion was coming from. And yeah, that harness seems to be exactly like the Tantus Velvet Harness: https://www.amazon.com/Tantus-Vibrating-Harness-Dildo-Black/dp/B00GOB8OJS?th=1 Which is also a really good harness that won't break the bank.
