Depends ? Brand new vintage ? or brand new current manufacture ?
Current mfg prices are high, $500 & up in these parts, and there is a lot of hit and miss with reference to quality of fit & finish and some reliability issues.
New vintage could be an awesome deal for the right price, caliber is also a factor. 30-30 Win , 35 Rem, etc... need more specifics.
Don't think levers will be effected, but you never know ?
