I'm sure this could cause considerable debate, but IMO there is only one name that defines high-quality tripods: GITZO. I own 8 different Gitzo models in various sizes, some I've had for 30 years and they are as smooth and tight as the day I bought them.

My personal favorite is their model G1224-MK2 Reporter Industrial. It's heavy enough for studio work (up to 35mm and "light" medium format), and yet I find I can easily spend a day in the field with it for nature scenics & wildlife.
If you want a sturdy, general-purpose unit that is lighter in weight, perhaps for hiking or for use in cramped locations, I suggest the model G120 Gitzo Sport Performance. It's the llightest I would recommend for a camera as heavy as the E-10. I have NEVER found any value to the "table-top" types of tripod.
Whatever type or brand you decide to get, always get one that is much higher than you think you need. It's amazing how short a tripod can get when you need to set it up on uneven surfaces, stairs, or hillsides!
I also recommend getting a decent size ballhead for speed and ease of use. A standard 3-way pan/tilt head is great in the studio, but can be slow and cumbersome in the field or for following action. Gizto heads are excellent, well-made and, of course expensive. But, as a less expensive alternative I actually prefer Bogen heads for all my Gitzos.
For the G120 I would suggest the Bogen 3262QR Medium Ball Head w/Quick Release. For the G1224 I like the Bogen 3030 Basic Pan/Tilt w/QR or the Bogen 3437 3D Magnesium Head w/QR. {I do not recommend the Bogen 3413 Pro Ball Head w/QR for the simple reason that the design does not allow very precise positioning. The camera tends to move when you try to lock the head. Bogen needs to revise this design.}

If the cost of a Gitzo tripod is beyond your budget, the 2nd best option is one of the Bogen/Manfrotto tripods. Unlike most cameras, your tripod is a lifetime investment and there is no fear of obsolesence -- buy the BEST that you can!
