Yeah at this price buying individually would definitely be the move.
I priced everything out on currently available listings just for fun. On keh or ebay or various other sites that offer return policies, warranties, coupons, discounts, that make them preferable to customers to buying privately.
A6000 body only at KEH, $333. Goes for under $300 on this subreddit with a lens
18-105/4 G PZ on ebay: $416
30/1.4 at ebay, $250
60/2.8 at MPB, $169
55-210: $150 ebay for used once, $130 KEH for very conservatively graded BGN grade
12/2.0: $209, theres a guy selling one on this sub for $200.
NP-FW50: $10 per for Sony OEM at KEH, not that theres any difference between generic wasabi/ravpower and sony branded, some prefer OEM though.
$1500 priced out individually searching BIN listings available right now on ebay, you could save even more money bidding on auctions on ebay rather than buying from BIN listings.
I guess if you add tax it becomes around $1600, but again you can get exactly what you want buying individually rather than be forced to buy everything.
