Only you can answer that question. Many gajillion bugs have been tied on that vise by novices and experts alike.
Sentimentality makes us wish we still had our Thompson. The Nor-vise we eventually "progressed" to, has all the bells and whistles and we would not be without it.
IMHO, I would not "progress" to a new vise until YOU found a "purpose" to do so in your tying. Such as maybe wanting to roll the fly for visuals or materials application or maybe wanting fast, easy hook holding capabilities or something....? THEN get the best you can afford and do it only once. There is a rotary type vise for under $100.00 that could serve you as well as any rotary type and you can spend conciderably more to aquire an in-line rotary that will do it ALL.
