(Left to Right) Zoom H1, Tascam DR-05, Zoom H4n
If anyone cares, here's the relative size of the Tascam DR-05 in between the Zoom H1 (left) and Zoom H4n (right). It's priced the same as the Zoom H1 and also lacks any XLR inputs. Although it's a bit larger than the Zoom H1, the Tascam DR-05 is just a better build overall. It has some decent weight to it too, so it doesn't feel very fragile. It's got many more features in the menu which is easy to navigate and obviously sounds great. The tripod mount in the rear has a metal insert (not plastic like H1), and i've had the same alkaline (the ones that came with) batteries in there for over a week now. So it doesn't drain over night like some odd Zoom H1 issues.
It's not as full featured as a Zoom H4n, but for the same price as an H1 it's a solid portable recorder. The Zoom H1 is still much lighter and smaller, and for those who are looking for a recorder to throw in someone's pocket with a LAV mic, it's still the way to go. By the way, if you're looking for an H4n the best deal was on the Manufacturer Refurb items. The first seller sold out, but there's one more seller with a few left.
