you could try other viral expression systems, such as vaccinia or Sindbis, in
mammalian cells. These can rival baculo for expression level, but will be just
as expensive to maintain. It really depends on your intended use, really. If you
want to make one big bucket of protein vs. several buckets over time vs. maybe
a good thimble-full, the necessity of correct processing/folding, and ease of
purification are all important criteria for your consideration. so, think about
them and re-ask the question. best of luck,
