I am in the market for new pipettes to use with my MTS-gel system. I currently have 2 old Tipmaster pipettes that Ortho sold us with the gel system. I have seen a brochure on the Ovation Vista adjustable pipette. It looks pretty cool and is ergonomically correct, which would be great for one of my techs who has a little bit of arthritis. Is anyone using this? If so, how do you like it? I am also considering the Biohit, but I have seen some bad reviews of this one (breaks down too soon) and it's more expensive than the Ovation and the Tipmaster. Thanks, Amelia
