- 28 cents 12x3 @ 1000 from UK n52 - [9]. This appears to be the best option.
- 7 cents 10x2 HK n52 (looks like 1/16" thickness) - [10]. While this looks cheaper, this is not because of the lower strength of 10x2.

Strength
- 12x3mm appears to be 8 lb - [15]
- 10x3mm is 5.5 lb - [16]
- 20x10x2mm is 4.8 lb - [17]
- 10x2mm n52 is 2.6 lb - [18]
- 12x2mm n52 is 3.8 lb - [19] - note - this is probably 1/16", or 1/2 the pull force of the 1/8" version (3 mm)
- 6x3mm n52 is 2.9 lb - [20]
- 6x6mm n52 is 4.2 lb - [21]
- 25x2mm n42 is 6.8 lb -[22]
- 6x1.5mm n35 - 1 lb - [23]
Notes
- 2 mm compared to 3 mm appears to be 1/2 as strong. 2 mm is really 1.6 mm, of 1/16", compared to 1/8", or 3 mm. That makes sense.
- Thus, it's more favorable to go with 3mm thickness.
Tested
- Ebay [24] - 25 for $11 - 48 cents.
