Should you go for a reasonable quality shoe, Loake for example, they will still be wrecked in short order by wearing the same pair every day.
If your job, or commute, entails a lot of walking, you may well be looking for a repair, if the original quality/construction, allows it, or, new shoes, within a few months. If the weather is against you, not letting the shoes dry slowly before you can polish and wear them again, will see them deteriorate even quicker.
Either way, you will not be able to do without a second pair.
IMO two pairs are a must, three would be better.
I do understand that budget can be the main factor, but a couple of pairs of Loakes will come in under £200, and will save you money in the long run, if you look after them.
