I'd recommend this pair. My home gym has it and it's great. Each DB goes from 5-100 lbs and the whole thing is $200. The paint chips but besides that it works great.
Hello. The dumbbells I got were these: https://www.amazon.com/gp/product/B0087T8UOE/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1
They work fine. great knurling, $219 after tax, ordered about 2 weeks ago.
Why stop at 50 lbs. when you could have 100!
Just for reference, I have these, and I'd say the only major drawback is that they are pretty damn long, which can make incline curls a little awkward. But yknow, great to have 200 lbs. for shrugs and calf raises.
