I bought a soda blasting set up (reservoir and gun) for use with my compressor and it was rubbish. Soda needs a lot of pressure to flow and it is messy to use. I now use a small cabinet with grit or glass beads and that works well with my hobbyist compressor. The cabinet won't take large parts such as wheel rims but it is good for small parts. Get the best you can afford. There are lots of Clarke 'clones' for sale on line. Make sure the one you get has a good light inside as parts can be hard to see in the grit storm! I use an old 'Henry' vacuum cleaner as the exhaust but I have to clean the in-built filter on the cabinet regularly to take away the dust.

I think you will find any small/medium compressor will run low on air when used for blasting.
I normally blast away until it runs down then move to some other job , painting ,cleaning etc while it recharges .
then go back to blasting and so on .

I agree and that is why anything but a large compressor won't power the soda hopper/reservoir tank for soda blasting.
I have a 2 and a half HP compressor and that does power the sandblasting cabinet continuously but the compressor runs almost all of the time, I have to wear wear defenders because of the noise of the compressor.
I suggest bigbird needs to make sure he has a compressor that is sized to the job.

Compressors are not classified by what pressure they can create but buy the of air they can provide. Home use without heavy duty cables and other things needed is about a 3hp 16cfm .then you need to remember its what it will produce continuously a good make that will be about 12 to 13 cfm cheap makes maybe down to 10cfm. You can run a cabinet with one that size but you need a blasting gun that will be compatible with the Compressor plus the size of the receiver thats the tank will give a more stable run time.its down to cost is buying the tools cheaper than sending them out plus the space it will take up

You can easily lose a third of the quoted cfm. Manufacturers/suppliers like to quote the nice high cfm figure and not the free air delivery (FAD) of their equipment. I used to sell SIP and went on a training course with them and back then they liked to quote the FAD. Advice was to check the consumption of the tool and make sure the FAD of the compressor would be enough to cope.

I'm in agreement with the comments above, its about airflow, I bought a 3hp compressor (supposed to flow 12cfm, realistically I'd guess more like 10cfm) it just about keeps up with my gun on small parts but a full motorcycle frame would be out of the question
