I am currently looking at replacing my 4 x Hydra 26s (not HD) however due to unforeseen circumstances I won't have the budget I would have had. I and have been offered a pair of 2.1/2 year old secondhand Oprphek Atlanik V2B's including Orpheck tablet and router at a very good price it seems. What are peoples thoughts on them and is there anything I need to know before considering buying them? I hear they are up-gradable and what about reliability along with the results etc? Unfortunately Orpheks are few and far between here in the UK and apart from the guy selling them (he has had to give uo keeping his tank) I don't know of anybody else using them (Radions rule here in the UK) and there is little information on them in the UK. Thanks.
