[Koha] Barcode scanner - keyboard wedge or not

[T & J Kotula]

Excuse my ignorance on the subject, but do I need to use a 'keyboard wedge'
scanner or can I just connect one to a serial (or USB) port and somehow
expect it to work with Koha - with the help of some software I assume, if so
which one. I will appreciate any hints on how to get the scanner working.

I haven't bought one yet, but want to make sure I will get the right one :-)

PS. I intend to use Code39 and a 7-digit book number with a checksum (an
excel spreadsheet with a formula was recently posted on this list)
PPS. Eagerly awaiting Koha 2.0


Thanks
