I would advise to get the best you budget can afford but also think o fthe resale value as well, as stated would be much easier to sell something that people know something about then a no name brand barbell. PLus you get the enjoyment on using quality barbell in the time you are using it which is always a benefit.
lifting for life, why sell barbells =p
Depends if you can afford it, I personally can't see the point in it unless you are competing, but some people like the ownership experience of something a bit special.
I use a $50 bar purchased recently for most of my lifting and it's fine, have had some of my home made bars for over 20 years and they are still fine.
I personally can't see how my muscles will tell the difference, it's not about fancy equipment it's about effort and persistence. Pick up heavy shit and lift it, no need to get complicated.
Its nothing to do with ownership or having something special or any crap like that, for me anyway.
I don't compete but I like getting stronger and I don't trust a shitty cheap bar to be squatting over 200, deads and rack pulling near or over 300kg. Its about saftey and using something that is actually designed for the job.
With those weights I would consider upgrading, but with my weights my bars are fine, once I squat 200 I too would upgrade, but personally I think that will never happen for me, due to injuries from my past, I am more that happy with where I got as it is.
If the op recons the most he will ever lift is 150kg then I cold see no point in buying an expensive bar for quite some time, and my $50 bar is 28mm and rated to 250kg, handles 180kg deads with ease, and will handle 200plus deads, I squat my 150kg with a 20 year old home made bar, and I am sure it will go well past 180kg with no issues for safety what so ever.
Do you guys think its worthwhile purchasing a premium barbell if it wont see weights beyond 150kg.
I like the feel of good quality iron in my hands
