Depends what you mean by quality. Unfortunately, PenBBS[0] has suspended shipments to India temporarily due to COVID, but for their price they are quite good. You may want to keep an eye on the page to see when they will resume.
In the US, there are sites like Goulet Pens, but that probably won't help someone in India.
As someone else pointed out, India does make some decent pens. Fountain Pen Revolution[1] has gotten quite popular for their flex nibs (much cheaper than other good flex nibs), and is very likely a relabeled Indian pen (they are manufactured in India). You can Google to find the manufacturer in India - they have their own line of pens sold locally. I'm not sure I would recommend FPR for non-flex nibs, and you probably don't want to use a flex nib for daily writing.
