This from the PPrune North America forum:
"Please refer to FAR 61.55(d) for the regulatory requirements for issuance of an "SIC type rating". Bottom line: If you have completed the required training, It's just a paperwork exersise. As stated previously, there is no practical exam for the SIC type. Your training records and a signed 8710 may be presented to a FSDO inspector. He should be able to issue a new temporary on the spot. This is the quickest and easiest way to go. FSDOs in the boonies may be less familiar with this procedure than those located in a major city. "
Definitely get the SIC type, it's free. If you want a full unrestricted type then you'll need to talk to Alteon. If they can do it for less than a few thousand bucks then I think it is money well spent. The beauty of FAA type ratings is that they are permanent. If that type can open a door for you later in your career then it could easily repay the cost.
