One more thing, There are some obvious underhanded , but legal, ways to log flight time that some people have mentioned her (safety pilot , sole manipulator, etc). But if you want to log time as SIC, you need to technically have one of two things. Either an aircraft that requires two pilots by type certification, or an ops specs that rerquires two pilots for operational or safety reasons. Since 91 operators dont use ops specs, having the required initial and annual training should suffice to any future employer as to the validity of your logbook. Especially if you both trained together as a crew and that training included CRM. IN that case, you are golden and nobody will ever question that 208 time of yours. So, in my opinion, if that 208 seat is being offered to you on a regular basis, and there is an opportunity to get a good amount of flight time in the thing, see if this operator will send you to Flight Safety with the other guy the next time he (or she) goes. Even if they wont pay for your training, it might be worth it to you to pay for it yourself.
