Like anything it comes down to what you want to pay. For me I love Springfields so much it is worth it to me to buy a $900 03a3 and pay $300+ to import it. On gunbroker right now there is over 100 Springfields available and it is like that every day. Granted some are sporters but up here you may see one really nice one once in a blue moon. Personally I have had a Mauser 98 and it was a nice rifle. If you plan to shoot I would go with a 1903 or a3 any day simply for the fact that the sights are better and you just can't use a sling properly with a Mauser. Add in the US martial history and it's a no brainer for me. ( but that's just me)
I have recently gotten rid of everything except a Garand, Smith Corona 03a3 and have a Remington 1903 getting built as well as a Remington 03a3 on the way from the US which will be my shooter. I'd sell the Garand too but I have too much time, effort and money into it to let it go.
I kinda agree with paying $1300+ for a 03A3! what did you get rid of, if I may
