Getting a Filco TenKeyPad number pad to work with Macs

Hi,

I have a Filco TenKeyPad mechanical number pad from the days when I was a Windows user. I've since jumped ship to Apple, owning an iMac and a MBP. As neither of these devices has a number pad, I would very much like to use the Filco as I have a lot of data entry to complete.

Is it even possible or worth the trouble? I read somewhere that you can use third party software to re-map the keys, but that seemed a bit daunting to me. Would it make more sense just to buy a Magic Keyboard with included number pad? Does Apple sell a dedicated number-pad?

Thanks.
