> The OBLIQUE holders is where the real price difference comes in. Part is because of the metalwork for holding the nib in the offset position. But part is simply the artistic work of the pen maker. Prices range from the $2 Speedball oblique to well over $100 for custom oblique holders. I use a plastic $13 Peerless Oblique, and it does just fine for me. Others like the wood $20 Century Oblique holder.
Those holder should really be considered the bottom of the pile for oblique holders, i.e., the cheapest semi-serious holders. Above that price point is not just woodworking artistry. The better holders do not sacrifice writing performance for ease of manufacture. The pen makers are also pen users and their designs are expressions of the understanding of the user's needs. That said, the Peerless Oblique is not a bad holder, but I'd pay another two bucks and get the Speedball Deluxe, which I think feels better under the fingers. Still, the 'bargain' holder on my desk is the Zanerian (style) Oblique holder designed by Del Tysdal (available from the usual suspects). It's a very nice holder and costs under $40, about the same price as a Lamy Allstar.
