Not sure about prices for 3ft tanks.. pls help!

[qngwn]

hi all!

I'm looking to upgrade my 2ft tank after 2 years of fun with it.
so I'm actually looking for a second hand 3ft tank with stand.

prices range from 250 to 400 that I have found online, and thought that it is quite expensive that 4ft tanks are in the 100+ range.

but due to the lack of sellers for 3ft tanks, prices have indeed become
more ex than that of 4ft..

please advise the rough range of price!
although prices will vary according to age and condition, hopefully a rough guide here will help people be more informed of the Market price when purchasing a second hand tank set..

thanks in advance!
