Reasonably Priced Fuse Upgrade for Magnepan 3.7?

Hey everyone,

I recently acquired some Magnepan 3.7 speakers and wanted to start tweaking them, so I ordered some Mundorf M-Resist Supreme 1.0 ohm Resistors for $23 each, but I can't seem to find any hifi fuses that are reasonable priced.  Seems like hifi fuses start around $100 each, I need 4 fuses, and I don't want to spend $400 on a whim.  Can anyone recommend some fuse upgrades that are reasonably priced, maybe around $20 each?

Looks like I need two 2.5A fuses and two 5A fuses, large size.  I'd prefer not to bypass the fuses, so let's not get into that debate here... =)

Thanks!
Chris
