Between $50 and $100, you can start looking at proper beginner training gear: glove and protective gear sets, or first pieces of equipment for home training. This price range is ideal for someone who has recently started training at an MMA gym or is thinking about getting started.
This is also the budget range where checking the recipient’s size and experience level becomes increasingly important. Ill-fitting or unsuitable equipment won’t get much use, whatever the price. A complete beginner’s set is often a safer choice than buying a single piece of equipment for someone just starting out.
