The term recreational rebreather was a marketing ploy. Any rebreather you can name uses basically the same principal of operation, has the same types of pitfalls and is extremely intolerant of lackadaisical divers as the accident list attests to. Recreational, technical, whatever, it's the same animal. Just buy a good solid rebreather with a good solid track record (10 years in the business is a good indicator) and learn to dive it. Do your maintenance, checklists, and training and you will do well. One piece of dive gear I consistently say I'm glad I bought was my megalodon rebreather. Best piece of kit I've ever owned.
