How to fix this sentence?

Thankyou everyone. This was first query here and now I know who to turn to when in doubt.

I know the expression; it just didn't seem relevant to the sentence as a whole.

I will revisit this but there is some contextual information before this line in the article, so it does not look bad as a whole. Thanks.

Just a rephrase to make 500 refer to products and not people:
"There sure is tech savvy among the crowd who bought the first lot of five hundred products without causing a big dent in their wallets."

I agrees its about the first 500 products purchased by tech savvy people

Could the problem be with tenses?

There sure is tech savvy crowd among first lot of five hundred who bought <product> without causing big dent in their wallet.

My try:
There sure was the tech savvy crowd who were among the first 500 to buy the product without causing a big dent in their wallets.

There sure is the tech savvy crowd who will be among the first 500 to buy the product, without making a dent in their wallets.
