Query: Uniball vision elite pen

When I barrowed this pen from a friend I was so impressed I drove down to Office Max and bought a few. This is probably the best pen you can get under $20. It writes VERY smooth, no scratchy lines, but no blotches either--just smooth consistant lines. It feels good in the hand and it's quite sharp-looking too. Arguably, these pens are a bit expensive, $9.00 for a pack of four, but their quality makes it worth it.
