I'm on the el-cheapo team, too.
I buy enough of the turkey injection stuff each year (i fried 14 turkeys this year) that I end up with 3-4 of em.
I broke down and splurged on some that were just a tad more expensive because they had metal threads. I'm pretty sure i got em on clearance for $1-$2 apiece. They are a little nicer than the "freebies" but both work just fine by me.
