Not wanting to spend more than £350 - £400
Get on to Ebay, plenty of second hand racks and weight sets, you will get more for your money.
Do you have space for a full sized rack?
Not wanting to spend more than £350 - £400
Could you fit a half rack? e.g.
I have that squat and dip rack, you couldn't take it apart enough to go under a desk, you can pull the 2 halves apart and stack them but the cross bar is bolted tight
I know I'd not be getting an ideal home gym set-up here, but I just want something to let me barbell bench and back squat at home.
Is there a particular compelling reason you want to back squat and barbell bench at home??
If you are so strapped for space that you are looking for a setup you can put away between workouts its going to be a real pain in the ass to do anything meaningful. The weights take up a lot of room on their own then you add the stands and the bench and you honestly will need at least 9ft x 8ft area just to work in.
if you are adamant that working out at home is what you want to do, then forget a squat rack and barbell benching and invest in a set of adjustable dumbbells, and a folding bench.
Then of the 2 racks you linked above the first is your best option, but if you want it to be storage friendly you will have to take off the orange cross bar each workout. Looks like its 3 bolts a side so wont take forever, but heck I wouldn't want to have to do that.
I would rather get a bike and cycle to the gym lol!
Would this be any good for you?

Regarding dumbbells take a look at the PowerBlock Sport 90 EXP
Yes there expensive but a lot less faff than ordinary dumbbells, and a pleasure to use.
Why do you want a smith machine?Any opinions or alternatives on something like this?

It seems to have all the options Im after, but not sure if the smith bar would get in the way when doing other exercises.
Also, I dont know what are good brands to look out for.
The price is about my budget, and I have plenty of space for something like this.
